RAIL ANCHOR.

My invention relates to rail anchoring devices for resisting the longitudinal move nient of railroad rails.

The principal object of the invention is to provide an improved rail ancho'riwhich may be made from a single piece of metal out and bent to the desired configuration,

which device, when applied to the base flange of a railroad rail will be distortedso as to maintain its operative position on the rail by spring pressure', but which will take a positive hold on' the rail to resist longitudinal creeping movement -of the rail. another and moreispec'ilic object isyto provide a o'iielpiece' anchorv ofthe above gen eral type in which the'fleXib'le portion of the anchor is relatively long so that the distortion of the anchor during its application to a iail will not produce a permanent set in the flexible portion oftlieanohor. v

The invention consists'lin' the new and im# proved construction hereiiiaftei' described and claimed for carrying out thefabove stated objects and such other' objectsofthe invention as will appear from the detailed description ofthe embodiments shown' in the accompanying drawings.

railroad rail the anchor device Referring first to F igs.` 1 t-o 4 inclusive wherein I have shown one embodiment of the invention adaptedv to' be driven transversely of the rail from one side thereof to its rail gripping position. This embodiment is made, preferably, from aflat strip of spring metal, the upper edge of which is recessed toy forma shoulder 10 at one end of the device and a jaw 11y at the other end. The end 12 of the metal strip is provided witha recess 13, which recess forms upper and lower'jaws 14`and 15. The" endportion 12 of the anchor is bent to form a loop 16 so th'at the jaws' 14 and 15 may bel fitted over the edge Vof the rail base and grip the same adjacent tlie`.jaw 11l Vof the anchor. T he' loop 16 is so formed, however, that the upper and lower jaws 14 and 15 are normally out of alignment with the jaw 11 and the upper edge' 1T of the body', when the anchor is fiee of the. rail. L'l:"r'eferably the jaw 1'4 extends' below the lower edgeof the jaw 11 and the upper edge 'of the jaw 15 extends downwardly and inwardly below' the upper edge 17 of the body of the anchor so that it" is necessary, in applyingfthey anchor, to force' the jaw v14l upwardly with relationy to ing the anchorto a rail, the body 18 ispassed beneatha rail bas'ej and the' jaws 11 and 14 are hookedover the upper edge' 19 of the rail base flange.' the anchor,`4 tlie sliould'er 10 is beneath the railbase substantially as shown in Fig. 2. The; end olf the loop may be struck with'a sledge o'i` other suitable implement so as to'y drive the anchor transversely of the raill until the shoulder 10 snaps up over the edge 2O of" the rail base.l During' this transverse movement ofthe anchor, the` jaw 14 is forced up on theinclined surface 21 of the rail base so as tosubject the loop .16'to' a torsionaly stress andthereby niove the jaws 14 and 15 from their oblique position into alignnient respectively withk the jaWv11 and the upperedge 17 o'f the' body. The torsional stress'tojwhich the loop is subjectedtexerts pressure upwardlyagainst the bottom of the rail baseV adjacent theshoulder10 of the anchor aridv also tends to tilt the jaw'11`and the upper 'edgel of the body labout an axis' trai'isversely of the rail sov as to effect a shacklev grip on the top and bottom surfaces 0f' the rail baseA flange.

In this'. initial position of In Fig. l of the drawings I have shown the anchor positioned on, the rail base so `that the loop portion only bears against the vlO of the anchor nearer the tie and thereby effects a positive'shackle grip of the shoul-v der l0 and the vertical `surface 25 of the of the base flange of the railj When the anchor is applied in reverse position so that thebody bears flatwise against the vertical face of the cross tie, any tendency. of the rail to creep toward the cross tietends to rock the jaw ll and the upper edge 17 of the body to effect a positive shackle grip on the. top and bottom surfaces of the rail base.

In Figs. 5 to 7, inclusive, of the drawings, I have shown a modified embodiment in which the device is flexed 'transversely and vertically of the rail during its application. This modification is made from a blank 26 of the configuration shown inFig. 7. The jaw 27 is bent at an angle to the body, preferably in a direction away from the cross tie, as shown in Fig. 5, and is formed so as to bear at the end 28onthe top surface of the rail base. The vertical edge 29l at this end of the anchor bears against the vertical edge of the rail base. The otherend of the blank is provided Vwith a shoulder 30 adapt-- ed to engage the vertical edge 3l of the rail base.V formed `with a jawv 33and the end is bent to form a resilient loop 34C so that the jaw 33 may be forced outwardly with respect to the edge of the rail base, to snap over the upper edge of said base. The extremity is so coiled that the lower surface 34 and the jaw 33 have to be iiexed upwardly to engage the jaw 33 over the edge of the rail base flange.

In applying the modified embodiment to a rail, the jaw 27 is hooked over one edge of the rail base and the shoulder 30 is positioned adjacent the vertical face of the opposite edge ofthe rail base. In this position the end of the loop 34 maybe forced outwardly with respect to the edge of the rail base and also forced upwardly so as to move the-jaw 33 into engagement with the upper surface of the rail base. The outward and upward movement of this end of the anchor torsions the loop portion thereof so as to tend to tilt the extremity 28 of jaw 27 into spring gripping engagement with the top surface of the rail base.

The modified form of anchor is illustrated The extremity 32 of the blank is in the drawings so that the loop portion direction toward the crosstie 24a tends to i Vcarry the angular jaw 27 nearer the cross tie ai d thereby effects a shackle grip of the shoulder 30 and the vertical portion 29 of the anchor on opposite. edges of the rail base. The torsional stress to which the loop portion 34 is subjected holds the shoulder 30 up in its operative position so as to insure a positive shackle grip during the presence of any creeping pressure.
